CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 291,985, dated Januar] l, 1884. l Application filed October 22, 1883. (No model.)

Be it known that I, DAvID E. MORGAN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and `useful Improvement in Oar-Couplings, of which the following is 'a specification.

My invention relates to that class of carcouplings which are designed to be self-acting, and intended to prevent the dangers which are always imminent when the personcoupling is compelled to be between the colliding cars. I attain this object by the device illus-v trated in the following drawings, in which- Figures l, 2, and 3 show vertical longitudinal sections through the center of the draw-head, Fig. 1 showing the pin ready to engage the link, and Fig. 2 showing the pin engaged with the link and the different positions at which the link can be held by the pin and dog preparatory to coupling. Fig. 4 is a perspective view of the spring-dog which holds the coup ling pin and link in desired positions. l Fig. 5 is a separate view ofthe coupling-pin in its most desirable form. Fig. 6 shows a section of the under side of the draw-head with the slot for the coupling-pin.

Similar letters refer to similar parts several views.

A is an ordinary shaped draw-head, having a guide, c, cast around the coupling-pin hole or slot on the top of the same, and of sufficient height to keepthe coupling-pin in a perpendicular positionwhen drawn up. The couplingpinshould be, by preference, of ovalshape in its cross-section, with the transverse diameter placed to receive thestrain when drawing. At its lower end u,is a hole through its crossdiameter, which receives a small cross-pin, f, after it has been passed through the upper slot at e, and which is inten ded to prevent the coupling-pin from being drawn up higher than is necessary to allow it to rest on the spring-dog B, a seat or recess, h, being left around the coupling-pin hole in the socket of the drawhead for that purpose.

B is a spring-dog, which fits into the socket of the .draw-head, its face or outer end, g, freely filling up the mouth of the socket inside the iiare. The faceof the dog is curved inwardly on its horizontal line to coincide with the flare of the entrance to the socket of thedraw-head,

in the as shown in Figs. 3 and 4, the object of this curve being to compel thelink to seek the center of the draw-head when about to couple, so that the coupling-pin has the ,f frearest` possible certaintyof engaging it. The vertical section of this dog-face has three curves, or perhaps, rather, it is formed of one general outward curve, with a concave groove cut through its center, dividing it into two (la k) convex sections next the walls ofthe socket, and one (j) concave section in the center, the special ob- `ject of which is to hold the coupling-link in any desired posit-ion, as shown in Fig. 2, so that acoupling may be made with a car higher or lower with as much certainty as when level. This is accomplished by thepressure of the spring-dog holding the coupling-link tightly between its face and the coupling-pin. Another and primary object of this dog is to allow the coupling-pin to rest on its upper side, when set for coupliiw, as shown in Fig. l. This dog is made and secured in its place as follows: The face which fills the socket of the drawhead is made of sufficient depth only to secure sufficient strength. The rest of the bod of the dog is of uniform height with the face, and only a little longer than the requirements of slot b, or its necessary movement in coupling. All unnecessary material is removed from the body of the dog equally each side of the slot b, and it is extended by a round post, E, from its center of about the same length as the bod This post is fitted to move freely in the hole Z, castin the block D at its center, and is surrounded by a spiral spring, d, which presses the dog outward from the end of said block until held in its proper place for coupling by the screw-pin c impinging against the end of the slot b, holding the face ot' the dog in the proper position to receive the link, and allow, ing the coupling-pin to rest on its top, ready for a selfconnection. tapped through t-he t-op of the draw-head, just over the inner end of the slot b, when the dog is set for couplingv and extends into said slot sufcientfor the object intended. Itis not designed to impinge against the other end of its slot, for the dogs movement at that end should be limited by the body of the dog, the spring d, and the block I).

The slot e on the bottoni of the draw-head need not' be shaped as shown in Fig. 6. Any

This screw -pin c is IOO slot allowing the pin to pass freely will ausw er.

The Working of this device is sufficiently evident from the foregoing.
